Maroon 5 frontman Adam and the 'Superbad' actor hit the high-rollers' tables at the Hard Rock Hotel and Casino in Las Vegas last Friday (28.06.13), where they were on a massive losing streak - until an army of sexy swimsuit models came to save the day.

As soon as Adam's new squeeze, Sports Illustrated model Nina Agdal, turned up with a group of her most attractive model pals, the boys' luck started to change.

According to the New York Post, Jonah was overheard moaning they were ''both down $15,000'' and he hoped the bevy of beauties would ''work as good-luck charms.''

Nina and her friends Julie Henderson, Genevieve Morton, Kate Bock and Alyssa Miller - who were dressed to the nines after coming straight from Sports Illustrated magazine's Summer of Swim Bash at the Wynn hotel - were only to happy to oblige and encouraged the pair to win back their losses.

While it is not known whether the duo managed to make back their money, eye-witnesses say they appeared extremely ''unfazed by the losses''.

'The Voice' mentor Adam certainly isn't strapped for cash, having just sold his Los Angeles bachelor pad which for $3.5 million. The 'Payphone' singer has upgraded to a bigger mansion, forking out $4.83 million on a 6,539-square-foot ranch-style home in a gated Beverly Hills enclave last autumn.
